Abstract: 370,722. Thermionic cathodes. M-OVALVE CO., Ltd., Marconi House, Strand, London, MACFADYEN, K. A. and RYDE, J. W., of General Electric Co., Wembley, Middlesex. May 29, 1931, No. 15789. [Class 39 (i).] A cathode consists of a thin layer of an alkali metal on an oxidized support wire wound helically on a core of relatively rigid material having oxygen in its insulating surface. The core 1 may consist of a molybdenum wire 0À2 mm. in diameter which has been flashed in vacuo, coated by dipping in a finely divided suspension of kaolin and alumina in distilled water, and heated in vacuo to sinter the coating. The helix 2 of tungsten wire, 0À06 mm. in diameter, is heated in oxygen, after which caesium vapour is admitted and short lengths 4 of nickel wire spot welded on the ends to form leads. In a modification, the ends of the tungsten are not flashed, so that they remain ductile. The core and helix are then clamped by a nickel lead-in wire, and the other lead-in spot welded to the helix after stretching the helix so as to allow the end of the core to project between two turns. The cathode is spot-welded to supports 3, 5, the valve is baked and evacuated, and the metal parts heated to de-gas them. The helix 2 is heated and oxidized by admission of oxygen. A getter pellet 10 is volatilized to clean up the valve and caesium is then released from a pellet 11, and adheres to the helix 2.

Title: Improvements in electron discharge apparatus
IPC: H01J31/06
Filed: 1945-06-22
Abstract: 593,674. Electron beam apparatus ; thermionic distributers. W E S T E R N ELECTRIC CO., Inc. June 22, 1945, No. 15973. Convention date, June 29, 1944. [Classes 39 (i) and 40 (v)] An electronic switch comprises a cathode 11, a grid 12, tray-shaped anodes 13a-j mounted on a circular arc concentric with the cathode, with a screen 14 having an aperture opposite each anode and magnetic polepieces 17 to provide a constant focusing field. Each anode is connected through a tap on windings 18a and 18b on a magnetic core 30 to the positive terminal of a battery, the negative terminal of which is connected to the cathode by way of ground. When an auxiliary coil 19 is energized from a pulsing circuit 21, the beam is deflected on to another anode, the direction and amplitude of deflection being dependent on the polarity and magnitude of the field due to the pulse. A circuit through the anode selected is completed and a field set up due to that part of the coil 18 energized, which is arranged to be of sufficient intensity to hold the beam on that anode in the absence of the pulse. A second pulse causes the beam to select another anode and the circuit completed again gives a field of intensity sufficient to hold the beam in that position.

Title: Improvements in or relating to gun-ammunition cartridges and to projectile and cartridge assemblies
IPC: F42B5/38
Filed: 1940-11-01
Abstract: 569,129. Gun cartridges and projectiles. SMITH, W. H. Nov. 1, 1940, No. 16003. Divided out of 572,545. [Class 9 (i)] A cartridge particularly for muzzle-loaded guns, comprises a twopart case, the front part of which a has a cylindrical wall b, of smaller diameter than the gun bore, within which is secured the flanged edge of a back-plate f. The front and back parts are additionally connected by a central stem c which receives a priming charge and a primer e. The stem has a screwed extension k by which the cartridge is connected to the base of the projectile. On discharge, a pressure is built up within the cartridge which finally disrupts the joint between the front and back parts of the case and expands the wall b into gas-sealing contact with the bore of the gun ; the back-plate f is deformed, as shown in dotted lines, and the case leaves the gun attached to the projectile. Specifications 131,596 and 143,267, [both, in Class 9 (i)), are referred to.
Patent GB-769329-A (GB)
Title: Improvements in and relating to pneumatic percussive tools
IPC: B25D9/08
Filed: 1954-05-31
Abstract: 769,329. Percussive drills; LEAVELL, C. May 31, 1954, No. 16076/54. Class 124 A vibrationless pneumatic percussive tool comprises a cylinder and a piston, means for producing a constant force acting on the piston in one axial direction, gas pressure producing an intermittent force acting on the piston in the opposite direction at predetermined cyclically repeated times to overcome the constant force, the latter comprising the entire recoil-producing force acting on the cylinder. As shown, the tool comprises a cylinder in three parts 20a, 20b and 20c, a piston 29 and an anvil 27. The part 20a. has an inwardly directed sleeve 21 which is subjected to a constant pressure from a supply of compressed air from the outer tube 50 of a coaxial air pipe. A valve 44, operated by a lever 38 in a handle 34 on the part 20a is opened to admit air at a higher pressure than the constant supply, from the inner tube 49 of the coaxial tube to a rotary valve 70 which is driven by high pressure air bled from a bore 93 in the anvil 27 through a bore 59b, its speed being regulated, by a valve 83. In operation, a steel 28 is inserted into the anvil 27, the piston 29 is maintained in contact with the anvil by the constant air pressure and, on opening the valve 44 high pressure air is admitted through the rotary valve, through the bore 94 in the anvil to the underside of the piston which is raised against the constant pressure. The rotary valve, which is provided with a series of slots which control the admission of high pressure air below the piston and the venting of the space below the piston, cuts off the supply of high pressure air which is allowed to expand to atmospheric pressure. The constant pressure air-then begins to move the piston downwards and at the same time the rotary valve vents the space below the piston to atmosphere: and the piston strikes the anvil. The rotary valve is arranged to allow two blows per revolution. The anvil is free to slide in the cylinder and the operator,must apply sufficient pressure to the tool to prevent the anvil sliding to the end of its stroke. When the anvil does reach the end of its stroke, as the steel penetrates the work, the bores 94 in the anvil are opened to atmosphere through bores 85 in the part 20c and the piston remains stationary at the bottom of its stroke. A counter weight 78 is mounted to reciprocate in a cylinder in the part 20c, a cam, driven bythe rotary valve and having a sinuosidal groove 77 on its outer surface co-operating withpins 78a, 78b on the weight reciprocating the weight in the opposite direction to the piston to counteract any residual vibration. The weight of the piston may be increased by adding further portions and, to accommodate the increased length, additional lengths of the part 20b may be fitted. The constant pressure chamber of the part 20a may be provided with a pressure relief valve, Fig. 12 (not shown). In a modification, Fig. 13 (not shown), the constant force may-be supplied by a coiled spring.

Title: Improvements in or relating to reciprocating steam engines
IPC: F01B17/04
Filed: 1922-06-10
Abstract: 181,380. Junod, P. June 10, 1921, [Convention date]. Engines working on special cycles. - In uniflow and other engines, the formation of a loop in the indicator diagram by the overcompression of residue steam on the return stroke of the piston is prevented by varying the timing of the inlet valve, and in some cases also of the exhaust valve, according to the pressure of the exhaust steam. The inlet valve is opened when the pressure of the residual steam is equal to that of the steam supply, and may be arranged to open either at the end of the return stroke or at the beginning of the working stroke, the residual steam in the latter case having expanded again to the pressure of the steam supply. The engine may be provided with independent gear for varying the cut-off. The valve gear h of the inlet valve is controlled through a link g and lever e by a piston b, which is acted on either directly or indirectly, by the pressure of the exhaust steam, against the action of a spring d. The valve gear i of the exhaust valve may also be controlled from the lever e. In the latter case, with low exhaust pressures the apparatus is so arranged that the control is effected primarily by varying the timing of the exhaust valve, while with high exhaust presssures the timing of the inlet valve is principally affected. For this purpose the inlet valve-gear may be adjustable, e.g. by means of a piston k, after the piston b has been adjusted to its full extent.

Title: Purification of alkaryl sulfonates
Inventor: FEIGHNER GEORGE CHRISTY
IPC: C07C309/31
Filed: 1957-05-23
Abstract: Substantially colourless alkaryl sulphonates are prepared by sulphonating an alkaryl hydrocarbon with a sulphonating agent consisting of sulphuric acid, oleum, chlorosulphonic acid or sulphur trioxide, separating any spent sulphonating agent from the resulting alkaryl sulphonic acid, bleaching said sulphonic acid by treatment with hydrogen peroxide, neutralizing said sulphonic acid and recovering the alkaryl sulphonate.  Suitable alkaryl hydrocarbons are those obtained by alkylating benzene, toluene or xylene with an olefin, alcohol or alkyl halide, which may contain 9 to 18 carbon atoms, in the presence of a Friedel-Crafts catalyst.  Between 0.3 to 3.0 weight per cent of 100 per cent hydrogen peroxide, based on the weight of alkaryl sulphonic acid, may be used in the bleaching process, which is carried out at a temperature between about 20 DEG and 75 DEG  C.  In examples dodecylbenzene was sulphonated with oleum or sulphur trioxide, the resultant sulphonic acid treated with hydrogen peroxide and neutralized with aqueous sodium hydroxide solution. The colour of a solution of the resultant alkaryl sulphonate was compared with that obtained from the unbleached acid or when the sodium dodecylbenzene sulphonate was bleached.
